AJAX Script not working in IE

[wpt394]

I am running a code that works just fine in Firefox, but seems to have trouble in IE. The basic idea is that a travel search process is initiated with one ajax call, and a 2nd ajax call 'updates' the page with the results that have been retrieved thus far. This 2nd call loops until the first call (the search) is complete.

Everything works fine in Firefox, but in IE, the 2nd call doesn't work until the very end when the 1st call is complete. In other words, in IE, you don't see the results being continuously updated -- you just see the final set of results at the end.

Now, the search (i.e. the first AJAX call) does use the cURL library with php, which may have something to do with it. I thought it may be the 'two simultaneous connection' thing, but why would it work in Firefox without any problem??

Here is JS I'm using...

 
function startSearch(sess, inmonth, inday, inyear, outmonth, outday, outyear, sort, loc1, loc2, loc3, loc4, loc5, starslm, stars, minp, maxp, exp)
{
    var loadingtext    = '<img src=/images/loader.gif><br>Please wait while we process your search...<br>Searches may take up to a minute.'; 
    document.getElementById("loading").innerHTML=loadingtext;
    repeatSort = 1;
 
        var url="dosearch.php";
        url=url+"?sess="+sess;
        url=url+"&inmonth="+inmonth;
        url=url+"&inday="+inday;
        url=url+"&inyear="+inyear;
        url=url+"&outmonth="+outmonth;
        url=url+"&outday="+outday;
        url=url+"&outyear="+outyear;
        url=url+"&sid="+Math.random();
 
        searchRequest=GetXmlHttpObject();
        searchRequest.onreadystatechange=function(){
            searchReqChanged();
        }
        searchRequest.open("GET",url,true);
        searchRequest.send(null);
    getSorter(sess, sort, loc1, loc2, loc3, loc4, loc5, starslm, stars, minp, maxp);
}
 
function searchReqChanged(){
    if (searchRequest.readyState==4)
    {     
        repeatSort = 0;
    }
}
 
 
function getSorter(sess, sort, loc1, loc2, loc3, loc4, loc5, starslm, stars, minp, maxp)
{
        var sesst= escape(encodeURI(sess));
        var url="sorter2.php";
        url=url+"?sid="+Math.random();
        url=url+"&sesst="+sesst+"&sort="+sort+"&loc1="+loc1+"&loc2="+loc2+ "&loc3="+loc3+"&loc4="+loc4+"&loc5="+loc5+"&starslm="+starslm+ "&stars="+stars+"&minp="+minp+"&maxp="+maxp;
        sorterRequest=GetXmlHttpObject();
 
        sorterRequest.onreadystatechange=function(){
 
            sorterReqChanged(sess, sort, loc1, loc2, loc3, loc4, loc5, starslm, stars, minp, maxp);
        }
 
        sorterRequest.open("GET",url,true);
        sorterRequest.send(null);
}
 
 
function sorterReqChanged(sess, sort, loc1, loc2, loc3, loc4, loc5, starslm, stars, minp, maxp){
    if (sorterRequest.readyState==4)
    { 
        document.getElementById("results").innerHTML=sorterRequest.responseText;
 
        if (repeatSort != -1){
            getSorter(sess, sort, loc1, loc2, loc3, loc4, loc5, starslm, stars, minp, maxp);
 
        }
        if (repeatSort == -1){
            var finished = 'Search Complete!';
            document.getElementById("loading").innerHTML=finished;    
        }
        if (repeatSort == 0){
            repeatSort = -1;
        }
    }
 
}
 
function GetXmlHttpObject()
{
var xmlHttp=null;
try
  {
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  // Internet Explorer
  try
    {
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
  }
return xmlHttp;
}

May be IE readystate will be "complete" rather than 4

function searchReqChanged(){
    if (searchRequest.readyState==4 || searchRequest.readyState=="complete")
    {   
        repeatSort = 0;
    }
}
